Well figure I ask ahead of time and get opinions, From too many horror stories I decided to stay away from mmr. PLEASE DONT TURN THIS THREAD AROUND AND SAY HOW GOOD/BAD THEY ARE MMR IS NOT AN OPTION HERE LOL. Anyway I was thinking livernois, sean hyland motorsports, or the good ol' aluminator from ford racing? if not any of those 3 I'm all ears. I want a built shortblock/longblock(havn't decided yet) good for 500whp+ that isnt shitty or gonna have to be sent back a week later for x amount of quality/balance issues. Btw this is for my 01 gt auto.
